Analysis of the transport protocol requirements for the SpaceWire on-board networks of spacecrafts

The paper gives an overview and analysis of SpaceWire oriented transport protocols. Also this paper considers the “Academician M.F. Reshetnev” Information Satellite Systems” general requirements for the Transport protocol to operate over the SpaceWire network technology. Finally, we propose preliminary solutions for some Transport protocol mechanisms

Second revision of the STP-ISS transport protocol for on-board spacewire networks

The paper provides an overview of the second revision of the Transport protocol STP-ISS, which is developed for SpaceWire on-board networks. Current R&D activity is performed by the specialists of SUAI and JSC “ISS”. The paper shortly compares two revisions of the specification and describes the main mechanisms and quality of service types of the second revision of the protocol. STP-ISS is planned to be used for the next generation spacecrafts

MEANS OF RESCUE FROM A HEIGHT DURING THE PERIOD OF SANCTIONS

The article discusses the means of rescue from a height, distributed on the territory of Russia over the past twenty years. A brief overview of devices and manufacturers depending on the part of imported content is carried out. There is made a forecast for the development of the situation of import substitution as for means of rescue of firefighters from the height

TRAINING TOWER BELAYING DEVICES

The article discusses the issue of using a belaying device on a training tower. The interpretation of normative documents in this area is given. There is presented the overview of possible belaying devices

STP-ISS Transport Protocol Overview and Modeling

The paper is concerned with the development of the Transport protocol “STP-ISS” for SpaceWire networks. Firstly we give a brief overview of transport protocols which are intended to operate over SpaceWire: RMAP, CCSDS PTP, STUP, JRDDP and STP. Hereinafter, the paper presents the first revision of the new STP-ISS transport protocol which was developed in accordance with the results of the overview and technical requirements to the transport protocol. Finally, we describe STP-ISS modeling, which was very efficient for the STP-ISS protocol development, testing, analysis and improvement. This paper describes three modeling directions: C++ reference code, SDL-specification and SystemC network model
